Methods for obtaining improved properties inmacroscopic material composites, however, have yet to be discovered. A major obstacle for effective control of macroscopic properties is the lack of suitable techniques to assemble and align nanotubes on the nanoscale. Over the past two years, methods have been explored to self assemble ionically-functionalized carbon nanotubes. This approach to assemble nanotubes focuses on optimizing tube aspect ratio and linking nanotube ends via ionic bonding interactions. Success of this method will lead to development of a selfassembling nanoscale methodology with potentially numerous commercial applications.
